The 90wt gear oil is no longer the recommended fluid. A few years ago the switch was made to hydraulic fluid. The instructions below were taken from my 2615 HST manual.
To change the front axle oil, put the tractor on level ground. Engage the park brake.
1. Remove the fill cap located on the axle housing, the differential drain plug located in the bottom of the housing and the gear case drain plugs located on the bottom of both side gear cases to drain the oil. For best results, drain the oil when the oil is warm.
2. Install the differential and both gear case drain plugs. Remove the oil level plugs located on both gear cases. Add the recommended oil through the fill hole until the oil begins to flow out of the level plug holes. Install the oil level plugs and the fill cap.

There is not a bit of difference. The gear box does not share fluid with the front axle.

I agree with AchingBack. 90wt is no longer recommended. Many manuals for the 2615 showed hy-trans as the proper fluid on one page and later in the book showed 90wt! I think either is fine really for the front diff, but for about 10 years now we have been filling them all with hy-trans.
sansone, the front diff will take a little over a gallon.
